Good day Nick,
I have added a link below which describes in detail how you can use the Limited Access Buttons. It describes what each button is needed for as well how to setup this feature.

If you would like all your users to have No limitation, this can be specified on the Person Card. On the Access tile, there is a box called Limited Access and here you can select No limitation.
Kind Regards,
